Securing devices from physical access

Protecting devices from physical access is crucial because it can allow an attacker or criminal to gain access to sensitive data or install malware on the device.

Use password protection or biometric authentication to lock devices when they are not in use. This will prevent unauthorised individuals from accessing the device if it is left unattended.

Keep devices with you at all times when traveling, or secure them in a safe location when not in use. Consider using a lock or cable to physically secure devices to a stationary object.

Privacy screens can help to prevent someone from seeing your screen when you are working in public places or when your device is left unattended. They do this by using a polarised sheet to restrict the viewing angle to approx. 30 degrees on either side. This can help to protect your data from being viewed by unauthorised parties.

Privacy screens help to prevent someone sitting next to you from viewing your screen.

Protecting devices from malware

Malware can include viruses, trojans, adware, worms, ransomware and spyware. Once infected, malware can steal, modify or prevent access to your data, on your devices. To protect our devices from malware, we need to do the following:

Antivirus software can help to detect and remove software performing potentially unwanted actions such as logging keystrokes, injecting malicious advertisements, installing ransomware or using the device as part of a network of other compromised devices, also known as a botnet.

Installing the latest security updates and patches can help to protect devices from known vulnerabilities and prevent malware infections through unexpected avenues (e.g. simply receiving a message or opening a website if a device has vulnerabilities, could lead to a compromise).

Be cautious when opening emails, clicking on links, or downloading files from unknown sources. These can often contain malware or lead to malicious websites. Instead, only download files from trusted sources and be mindful of the emails and links you click on.

To protect a device against malware infections, you should.

Don't install antivirus software because it'll slow down your device. Click on links or attachments in any email you receive. Keep devices up to date. None of the options are correct.

Types of home and work devices

Any device connected to a home or work network such as routers, IoT devices or smart home devices may expose the entirety of a network to cyber threats. To protect these devices, we should:

Secure smart home devices with strong, unique passwords and enable two-factor authentication whenever possible. Be cautious about the information shared with smart home devices, as this information can potentially be accessed by unauthorised parties.

Many IoT devices have security vulnerabilities that can be exploited by hackers. Keep IoT devices up to date with the latest security patches and updates, and consider disabling any unnecessary features or ports to reduce the risk of a cyber attack.

Keep routers and other network-connected devices, such as modems and switches, secure with strong passwords and periodic updates. Consider enabling WPA3 encryption for Wi-Fi networks to protect against unauthorised access.

Is the following statement True or False:
A compromised device can be used to onward attack another device on the same network.

Device network security

Avoid using public Wi-Fi networks, other users on these networks can potentially intercept your traffic and steal sensitive information. If you must, ensure you're using a Virtual Private Network (VPN) at all times.

Is the following statement True or False:
Connecting to public Wi-Fi networks is safe if you just avoid clicking links in suspicious emails.

Attackers who control a public Wi-Fi network can intercept your traffic and potentially steal sensitive information. We should avoid using public Wi-Fi networks wherever possible, but if there's no alternative, we need to ensure a VPN is in-use at all times to encrypt all traffic going in and out of the device.

Wrapping up

Protecting devices from cyber criminals requires a defence-in-depth approach to ensure the devices are physically secure, operate on secure networks and are able to prevent the execution of malware.
